The power supply of the drive motor 60 stops. At this time, the water passage hole 51a of the stator 51, the water passage hole 55a of the rotor 55,
And the water channel 45 communicates.

After the flow path switching valve 50 is set to the predetermined switching state in this manner, the drive motor 60 rotates in the reverse direction. When the drive motor 60 rotates in the reverse direction, the screw member 420 advances the nut member 410, and the cleaning nozzle 40 moves from the storage position to the standby position. At this time, the clutch member 610 of the clutch means 600 moves together with the cleaning nozzle 40, moves away from the first power transmission shaft 430, and the first power transmission shaft 430 is moved from the second position to the first position by the urging force of the coil spring 450.

From the storage position to the standby position.

The case where the buttocks are cleaned has been described above.
In the case of other bidet cleaning and soft buttocks cleaning (soft cleaning), the same cleaning is performed. That is, in the case of bidet cleaning, the first power transmission shaft 430 is driven from the first position to the second position by the clutch member 610 of the clutch means 600, so that power can be supplied from the drive motor 60 to the valve drive means 500. By rotating the drive motor 60, the rotor 55 is rotated from the reference position shown in FIG. 12A to a predetermined position between the bidet MIN state shown in FIG. 12B and the bidet MAX state shown in FIG. I do. At this time, the stator 51
, The water passage hole 55a of the rotor 55, and the water passage 46 communicate with each other.

When the flow path switching valve 50 enters a predetermined switching state, the drive motor 60 stops rotating, and then the drive motor 60 is rotated in reverse to return the first power transmission shaft 430 from the second position to the first position. Then, the cleaning nozzle 40 may be moved from the storage position to the standby position and further extended to a predetermined cleaning position. After the bidet cleaning, the cleaning nozzle 40 is moved from the cleaning position to the standby position, and further moved to the storage position.
Is rotated to the reference angle position, the flow path switching valve 50 is set in the initial state, and the cleaning nozzle 40 is returned from the storage position to the standby position.

And the water channel 47 are in communication.

When the flow path switching valve 50 enters a predetermined switching state, the drive motor 60 stops rotating, and then the drive motor 60 is rotated in reverse to return the first power transmission shaft 430 from the second position to the first position. Then, the cleaning nozzle 40 may be moved from the storage position to the standby position and further extended to a predetermined cleaning position. After the butt soft cleaning (soft cleaning), the cleaning nozzle 40 is moved from the cleaning position to the standby position, further moved to the storage position, and the rotor 55 is rotated to the reference angle position.
The flow path switching valve 50 is set in the initial state, and the cleaning nozzle 40 is returned from the storage position to the standby position.

As described above, in the nozzle mechanism 30 according to the present embodiment, the cleaning nozzle 40 is rotated between the storage position and the cleaning position by rotating the screw member 420 relative to the nut member 410. It is driven to a position.

In such a nozzle mechanism 30, if the relative rotation amount of the screw member 420 with respect to the nut member 410 fluctuates, or if the accuracy of the components of the nut member 410 and the screw member 420 is low, the cleaning nozzle 40 may not be used. However, if the amount of rotation of the screw member is appropriately controlled, and the allowable error and the assembly error of the nut member 410 and the like are made appropriate, the cleaning of the cleaning nozzle 40 can be performed. The position has less variation.

In addition to the amount of rotation of the screw member 420 and the accuracy of the components such as the nut member 410, the cleaning nozzle 40
There is no factor which greatly varies the cleaning position of the cleaning nozzle 40, and the configuration is such that it is easy to increase the positional accuracy of the cleaning position of the cleaning nozzle 40.

In the above embodiment, the nut member 410 is formed integrally with the nozzle cover 41 of the cleaning nozzle 40. However, the nut member 410 is
As long as it can move together with the cleaning nozzle 40, it may be integral or separate. Accordingly, when the rotational force of the drive motor 60 is supplied to the screw member 420, the screw member 420 draws out the nut member 410, and the cleaning nozzle 40 moves to a predetermined position together with the nut member 410.

When the cleaning nozzle 40 is moved to a predetermined position (standby position or cleaning position), the drive motor 60
